I've just put my original mobo back in its case, after having it tested. I'm told that its the same board. With the same ram and the same CPU. With the same HDD and everything as before. Whats unusual is that BC2 and windows is very sluggish, I'm not sure why its slow, it shouldn't be i7 with 5850. Haven't reinstalled windows since putting the motherboard back in, didn't think I needed to, as everythings the same. Can anyone suggest a reason for why its slow. Thanks in advance.
